FLEXIBLE BINDER-POST.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed November 13, 1911. Serial No. 659,963.

To all "whom it may concern Be it known that-I, HENRY C. MILLER,

of Milwaukee, Wisconsin, have invented a Flexible Binder-Post, of which the following is a specification.

This invention relates to binders of that class which are used more particularly for preserving documentary.

records Which are recorded in public oflices, such as real estate conveyances, assignments, corporation artlcles, etc. Such loose-leaf books areprovided with a fixed numberof leaves and a nonextensible cover and binding-posts, said binding-posts being detachably connected with the back at each side, and the mode of use being to remove successively the top leaves, copy the records thereupon and replace them serially in order in the back of the book.

The present application relates only to a special form of flexible post which is intended more particularly for use with the special binder disclosed in my-copending application No. 659,962 filed November 13, 1911.

The object of the invention is therefore to produce a nonextensible post inflexible in one plane and stiflly flexible in the other and having the requisite dimensions to give it not only the necessary rigidity and resiliency, but also to prevent it from cutting the leaves, and to give ita substantially uniform thickness. I

The nature of my said invention, and in what manner it may be performed is herein best illustrated in the accompanying drawings, wherein Figure 1 is a front view of a post constructed according to my invention; Fig. 2 is a side-view thereof showing in dotted lines its flexibility; Fig. 3 is a transverse section thereof; and Fig. 4 is a fragmentary perspective view of a loose-leaf book with one ofthe pintle-rods removed to open the back and illustrate the mounting of the osts.

p The reference letters" refer each to the same part in each figure of the drawings.

My improved post comprises, first a thin strip. of resilient metal, preferably spring-steeh-c; secondly, a pair of looped members I) forming pintle-eyes for the ends of the post; thirdly, a pair of flexible facing-pieces c mounted on opposite sides of member a; and fourthly rivets d'uniting the several pieces binder-posts for together. The facings c may also be glued or otherw1se secured to the strap 0 along the middle. For the facing-pieces c I have found leather the most suitable material,

and such leather is preferably metallized upon the outer side to give it a smooth surface, upon which the. edges of the apertures in the paper readily slide.

In Fig. 4, which illustrates the manner of use, is shown a loose-leaf book having covers e and the spring-back f, to which they are hingedly connected; also pintle- .shown' in the drawing). The sockets h are,

cut away as shown at 7' opposite the flexible posts k, whose end-eyes b are seated in the recesses j, the pintle-rods 71 passing through them. The length of the post is intended to be somewhat greater than that between the two covers, whereby the post la inthe open or closed positions of the book assume forwardly or rearwardly-curved 'po sitions; but the means for causing them to assume such positions in use, is not here shown, as it forms no part of the present invention.

The supporting-member of the post is the metal strip a, but this if used alone would not only not fill the apertures m in the leaves, which have to be large enough to pass over the eyes I), but also would be so thin upon the edges. that it would. cut the paper. The flexible and slightly extensible but 'nonresilient facings 0 provide the neoessary dimensions and at the same time add in one plane only, comprising a thin metalstrap, eyes upon the ends of said strap and facing-pieces of flexible and slightl extensible material on opposite sides 0 said strap. I y

2. A nonextensible binder post flexible in one plane only coinprising a thin fiat metal strap, a air of members secured. to

the opposite on of said strap, each of said members having an eye-shaped loop and a "pair of flanges including the end of said Qstrap between them, a pair of facing-pieces {on opposite sides of said strap and a pair "of rivets passing. through the respective ends of said strap,

acing-pieces and flanges and securing them all together.

3. A nonextensible binder-post flexible .in one plane only, comprising a thin metal 10 strap, eyes upon the ends of said strap and I facing-pieces of flexible and slightl extensible material on opposite sides 0 said In witness whereof I have hereunto set 15 my. hand in the presence of two witnesses.
